摘要：
The ITER torus and neutral beam cryopumps are complex vacuum pumps which will be designed to the build-to-print level stage for the call for tender for manufacturing. Although being completely different in size, the pumps share the same concept of cryosorption on activated charcoal. Thus, the design procedure itself can follow the same generic workflow. The requirements on the pumps are summarized and the status of design evolution is described. Both design packages require specific R&D for experimental clarification and design validation. Two examples for this approach are given, namely the characterization of the closing forces of the torus pump inlet valve, and the measurement of hydraulic resistance coefficients of hydroformed components.
